      Do you have another process using the tracking camera? It looks like it cannot open the tracking camera.

        @Chad-Sweet Launching on the VOXL Flight Deck I just received. Turned on, passed the wizard and get this error.
        What else can a tracking camera use?

          It would have shipped with everything tested and working. What do you mean by "passed the wizard"?

            @Chad-Sweet when connecting QGC, there was no odometry in the mavlink inspector. After that I ran voxl-configure-modalai-vl

              @Chad-Sweet now the odometry data is in the mavlink inspector, but x and y = 0

                Hello, When you ran the wizard, what did you enter for the camera configuration question, it should have been option 3 (hires+stereo+tracking) for a flight deck.

                Do you mind running voxl-vision-px4 manually in odometry debug mode to see if VIO is working and share the output? You can use this command:

                voxl-vision-px4 --debug_odometry

                Thanks!
